As a private pilot, comms are always on my mind. I have a Marine Corps HUMVEE that requires hearing protection. This solves that challenge and allows conversation while on the move
Must have for anyone working in the aircraft engine business.
Over abundance of information provided in this book that is explained in easily understood terms with easily comprehended imaging. Well worth the money.
I absolutely love this product. I have used it for years, but I have to say the shipping took over 30 days. Not sure why but it did so I’m not that satisfied with that part but I love the product.
